The said shaft 24 projectswithout the sides of said casing 23 and through the ordinary packing orstuiiing boxes 27 and is adapted to receive the double bell-crank levers28, the upper ends of which are connected by the transverse rod 29,`upon which is mounted the friction contact-roller 30, while the outerends or arms of said bell-crank levers are adapted to receive `thelaterally-adjustable Weights 3l, working thereover, aud

Mounted upon the rod orstem 37 and within the cylinder 33 is the float-cup 3.9,that is adaptedto rise and fallwith the rise and fall of the water in the adjacentcylinder l, and thereby vertically reciprocates said stem. To the upperend of said stem is connected a cross piece or bar 40, from whichdepends the opposite 'parallel arms 4l, working in the bearing-plate 42,secured to said tube 34, and said arms are adapted to receive thetappetsor collars 43, mounted thereon and carried by the reciprocation of thestem 37. A tilting lever 44 is pivoted centrally at 45 to the U-shapedcasting 4G, supported upon the cylinder 1, and is provided at its lowerend with the friction contact-roller 47 and the inwardly-proj ectin gstud or roller 48, that is designed to travel in the segmental slot 49,located in said U-shaped casting, and by means of which the movement ofsaid tilting lever is limited. An adjustable weight 50 is mounted uponthe upwardly-extendin g end of said arm or lever and is adapted to throwthe same sharply to the right or left after said lever has assumed avertical position in the manner to be presently described. The mainvalve-operating rod 51 is supported upon and horizontally over the topof the cylinder l and is connected at one end to the arm of the doublebellcrank lever 52, pivoted upon thebracket 53 at one end of saidcylinder, and said bell-crank lever is provided with the connectingfrictionroller, similar to roller 30, that is designed to be engaged bythe tappets 43, carried by the reciprocating stem 37, and thus causesthe said valve-rod 51 to be controlled from that side of the cylinder inone direction. The opposite end of said lever or arm 5l is providedwithJthe downwardly-extending tappet 55, that is designed to be engagedby the roller A branch 30 upon thedouble bell-crank lever 23 when thefloats have been carried to a horizontal position, and thusdraws saidrod in an opposite direction to that in which the same is drawn by thetappets 43. The said lever or arm 51 is further provided with theintermediate tappets 56 and 56, respectively, between which the`contact-roller 47 ofthe tilting lever 44 is designed to travel, andaccordingly as said rod or lever 51 is moved in either direction thesaid tappets carry the tilting lever 44 in a vertical position, in whichposition the weight 50 thereon overbalances the same and throwsthe leversharply to the right or left, according to `Whether the lever or rod 51is reciprocated to the left or right, and the sudden tilting movement ofsaid weighted lever sharply reciprocates the small valve-arm 57,pivotall y secured at 58 near the lower end of the tilting lever 44, andcarries the spaced tappets 59 and 59, between which the balanceValve-lever 60 depends and carries the contactfriction-roller 61, whichis engaged by either of the said tappets, according to the direction inwhich the tiltinglever falls, and thus opens the balance steam-valve 62,operated by said lever and located in the steam-pipe 63,communicatingwith the steamopening 22, located in said cylinder directly over thediffusion-plate 21. The said steampipe 63 is connected with any suitablegenerating-boiler, and is further provided with a supplementalhand-operated balancevalve 64, by means of which the steam is let on andentirely shut oit at the option of the operator. The cylinders l may beduplicated, if desired, and connected with asingle Water supply pipe bysuitable connection for the purpose of obtaining an increased volume ofWater, if desired.

The operation of the pump is automatic after the same has once beenstarted by the operator. Primarily the cylinder 1 is filled with asufficient quantity of water in order that the level of the same, may beabove the inlet spray-pipe 14, so that Water will stand within the samewithin the cylinder. The steam is now let on by the operator through thehand-operated balance-valve V64, located in the steam-supply pipe 63,and the lever 60 of the balance-valve 63 is turned by hand, so as togive a free passage of the steam to within the cylinder. The steamfilling the cylinder completely is almost instantly condensed by thespray-condenser 18, thus completely IOO IIO

filling the cylinder with Water and bringing the oats 26 up toV ahorizontal position, thus communicating motion through the bell-cranklevers 23 to the horizontal arm or lever 5l by means of thecontact-roller 30 of said bellcranks engaging the tappet 55 on said rodor arm, and through the smaller intermediate tappets 56 and 5,6,engaging thelower end of said tilting lever,causes the same to besharply thrown to one end of itslimit of movement, and thus starts theautomatic operation of the pump. It can be readily seen that after the'tilting lever has been caused to assume a vertical position the weightofthe ball or otherl tact-roller 6l upon the e'nd ofthe valve-operatinglever 60, thus opening the passage-ways and allowing the steam or othervapor'which may be used for creating a vacuum to pass immediately intothe cylinder, and, as can be readily seen, this primary operation causesthe valve-operating part to assume a position holding the same openwhile the cylinder is full. The steam being thus admitted into thecylinder impingcs on the concaved diffusion-plate and is equalized overthe entire surface of the water in the cylinder, which under thepressure of the steam is forced downward and out through thedischarge-outlet 6, through the valve-chamber thereover, and out throughthe discharge-pipe 12 to the place of delivery. The water being nowdischarged, the iioats 26 have descended to their lowermost limit andcarried the bell-crank levers 23 away from the tappet 55 on one end ofthe horizontal rod 5l, thus leaving the rod free to be acted on by thevertically-reciprocating tappets 4:3, engaging the double bellcranklevers 52, secured to the opposite upper end of the cylinder andconnected to the 0pposite end of said rod. The opening communieating thecylinder 33 with the main cylinder 3l governs the discharge of thewater, inasmuch as the cup 39 located therein falls with the fall of thewater, and when the water has fallen its allowed limit the said cup alsohas fallen with it and carries the stem or rod 37 downward, and therebycauses the tappets 43 4to iinpinge upon the roller of the bell-cranklevers 52 and draw the operating-rod 5l in the reverse direction, or tothe right, as illustrated in the drawings. rlhe tappet 56 upon said rod5l now carries thetilting lever to a vertical or perpendicular position,at which point the same sharply falls to theleft, or the reversedirection from which it fell to open the steam-valve, and thus carriesthe tappet 59a upon the valvelever or arm 57 to the right' and againstthe lower end of the valve-lever 60, thus throwing the same to itsvertical position, in which the ports or steam-passages are instantlyclosed. The water in the cylinder having been thus discharged to itsallowed level, the steam is thus shut off through the medium of thefloat-cup 49 in the manner just described, and leaves thecylinderlcornpletely illed with the steam or vapor. The4 instant thesteam or Ivapor is shut off the pressure of the water in thedischarge-pipe l2, extending above the top of the cylinder, forces itsway into and through the conductingpipe4 and upward through theperforated pipe 17 into the spray-condensing chamber 18 and through theradially-extending perforated s'pra'y-arm 19, the column of water n otonly giving force to spray the same within the cylinder, but thespraying is also accelerated by the uvacuum Vinstantly formed at theclosing of the'steam-valve. again filled by the watersucked within thesame by the vacuum through the suction-pipe 2 and suction-chamber 3, andthe alternate automatic operations of the pump are repeated in themanner j ust described,
